Big Pharma can outright say 'Yep, it was the vaccine that killed them.' and they will not be held liable. They were given immunity as part of Warp Speed. And as long as insurance companies don't make an exception in their contracts, they won't have to pay out on it. You know, having half the country die without having to pay death benefits on any of them would really prepare the insurance companies nicely for a great Obamacare follow-up plan. Once they explain this to the medical community, they'll both be laughing all the way to the bank.
